There was either a clear agreement that you were paying with a post-dated check, or there wasn't. If there wasn't, and we are to infer that the check was deposited right away, then that was a mistake on your part -- and, having received a rubber check, it is understandable that they want to be paid before they do any more work.
How would they know how you're shuffling funds between your accounts?Quoting OpinePenguin
You are probably being sued. Check with the local court. If you were previously served with a lawsuit and ignored it, they may have a court order.Quoting OpinePenguin
Is that supposed to be a surprise? You have their furnace and air conditioner.Quoting OpinePenguin
I don't know of a way for them to do so without a court order.Quoting OpinePenguin
If you are sued, you can try counter-suing and see what the judge decides.Quoting OpinePenguin
You did pay -- but with a rubber check.Quoting OpinePenguin
The issue you describe relating to non-completion is de minimis -- the charging of the air conditioner. Perhaps you should consider simply proposing that they come and collect from you a cashier's check for the balance you owe, to be tendered upon their charging the air conditioner.
If you knowingly accept a post-dated check, and it is NSF when you later deposit it, it is normally not prosecutable as a crime, as it is exceedingly difficult to demonstrate that the issuer of the check had criminal intent at the time the check was issued. There are few reasons to knowingly take a post-dated check other than because you understand that the issuer does not have funds at the time the check is issued; and there are even fewer cases in which accepting a post-dated check is a good idea.
That is not accurate. First, as of yet no crime has been charged, let alone proved. Second, the police are not going to hire contractors to remove HVAC equipment from a home as evidence. Third, there are no "criminal forfeiture" laws that would allow the state to claim ownership of the HVAC equipment, as happens with forfeiture, nor would the contractor that installed it want the state to do so.Quoting flyingron
